isn’t it wonderfull? everybody knows what is the best system for everybody else. seems, that i am an eternal starter in this hobby - i am playing in largescale with trackpower since 1970… i plan to stay with trackpower. because it is better for me. for me - not necessarily for you. and that is the whole point. we all want different things from and with our layouts. if it would be my pleasure to shuffle my rolling stock in yards, probably i would prefer direct control of my trains too. maybe even with battery power. but being as desorganized, as i am, i am afraid that i would not run trains everytime i would like to. simply for having forgotten to charge the batteries. but as i am so oldfashioned to like it if trains go roundy-round, i see no reason, why i should choose a system that needs additional attention from me. often it is mentioned, that the wiring of trackpowered layouts is one of the reasons not to use it. fine. the consequence of not wiring a layout seems to be, to run around the layout to operate switches by hand. so if i don’t want to run about, while running trains, either i build a pneumatic system or a cablesystem for my switches - or i wire them. if i wire my switches, that bit of additional wire splicing for trackpower once every decade or so, seems acceptable to ME. so if i do want to have the leisure to sip some liquid or to brag about my layout to guests while the trains run, for ME trackpower is the best. coming 25 of december it will be 40 years, that i belong to the congregation of the plug-worshiping brassies. i think, that it would be more probable for me to convert to the holy spagetty monster, than to succumb to the temptation of the unholy battery heretics. ploink (that was the sound of two cents on the table) edit: about shorting - one solution is to smear some silicone sealer into the gaps between rails.
